I maintain the local_externalzip plugin
I guess my question is, am I correct about "Other" plugins not being in AMOS? And, is there a way that we could get them in there, somehow?
There are several (n=16) plugins currently classified in the 'Other' category, which seemingly breaks the download folder naming, the online translation (AMOS), automatic install and update (and probably other helpful features). Davo Smith has raised this issue before with the Navigation Buttons plugin, but he has not yet seen a solution ( https://moodle.org/plugins/view.php?plugin=block_navbuttons ).
